LTE Multimedia Broadcast Multicast Service Provisioning Based on Robust Header Compression

Abstract

Cellular networks support a large number of wireless users with different service preferences in a variety of different channel conditions. To serve more users with better spectrum and power efficiency in Long Term Evolution (LTE) cellular networks, Multimedia Broadcast Multicast Service (MBMS) is an efficient service mode for multicasting to a large number of users. This work investigates user service provisioning of MBMS based on assessing the impact of the RObust Header Compression (ROHC) on MBMS service quality. In particular, we formulate a profit maximization problem for network operators that can optionally rely on MBMS. We propose a new user assignment scheme which aims to assign users into a MBMS group that utilizes shared, optimum ROHC parameters. We develop a Dynamic Programming (DP) algorithm for user assignment and ROHC parameter optimization to achieve high profit given insufficient amount of spectrum resources. Numerical results demonstrate the high profit achieved by the proposed user assignment and ROHC optimization in LTE MBMS.
